Reasons why you might want to change DNS to Google’s public DNS:
1. Better speed: mostly, Google DNS will grant you better speed than your ISP’s. However, this depends on how close Google’s DNS sever to you. This can easily be determined by using a free benchmarking tool; such as Namebench.
2. Better browsing experience: this is related to the previous point. If your ISP’s DNS is slow, you might experience times of total disconnection when certain websites fail to load.
3. Security: Google’s DNS supports DNSSEC to make sure that DNS requests are securely signed and correct.
4. Bypass geographic restrictions: when you change DNS to Google’s, you will be able to access USA-only streaming services; such as Netflix and Hulu, even in you are outside USA.
